Title: Electric power steering device
Inventor: TABUSE HIDETOSHI
IPC: B62D5/04
Filed: 1988-07-30
Abstract: PURPOSE:To prevent malfunction of a driving circuit by turning off a driving circuit of a corresponding power unit when abnormality occurs in a transmission line connecting a control unit and a power unit. CONSTITUTION:A logical control signal for controlling each driving circuit is converted from a logical control signal expressing 'ON' into the form of a pulse signal on the control unit 20 side by the first signal conversion circuit 22. The converted signal is sent through a transmission line to the second signal conversion circuit 14 of a power unit. When an input signal of the second signal conversion circuit 14 is not converted into a pulse signal because the abnormality occurs in the transmission line, the output of the second signal conversion circuit 14 becomes a logic signal of 'OFF' to stop a motor driving circuit 11.

Then the digital mean value is obtained from said addition value, and the mean value is set at the 1-pixel value corresponding to a picture of a prescribed area. Thus the amount of digital data forming screen can be reduced. This method is applied to a picture processor to perform the picture processing assuredly in real time with no use of a superhigh-speed computer. Furthermore the picture information of a prescribed area is compressed into each pixel value. Thus it is possible to obtain the accuracy high enough for a practical application despite a small amount of data.
